To calculate the sum of squares for a sample, you subtract the degrees of freedom of the sample from the variance of the sample. O add the degrees of freedom of the sample to the variance of the sample. O multiply the degrees of freedom of the sample by the variance of the sample. O divide the degrees of freedom of the sample by the variance of the sample.
